Java Annotation Processing - Runtime and Compile-Time Techniques

Explore the evolution and implementation of Java annotations in this 46-minute conference talk from Devoxx. Discover how annotations, since their introduction in Java 5, have transformed Java application development through both runtime and compile-time processing. Learn about runtime annotation processing using reflection, employed by frameworks like Spring and Hibernate for dependency injection and persistence operations. Understand the Java Annotation Processing API introduced in Java 6, which enables compile-time source processing and annotation handling, as demonstrated in libraries like Lombok and Dagger. Join Micronaut Framework committer Álvaro Sánchez-Mariscal as he demonstrates various annotation processing techniques through practical examples, unveiling the inner workings of popular open-source projects.
